Abstract Introduction: Aggressive MCL has a poor prognosis with a 21-40% complete remission (CR) after CHOP and a duration of response of only 10-16 months. More intense therapy could improve these statistics. Rituximab is effective in MCL and has minimal toxicity. Methods: A prospective phase II trial of R-HCVAD (considered to be one cycle) alternating every 21 days with R- M/A (considered to be another cycle) as described earlier (Ann Oncol. 13, suppl 2, 2002 #24). Prophylaxis with mesna, calcium leucovorin, prednisone eyedrops, G-CSF, antibacterial, antifungal, and antiviral therapy. CBC with differential and platelet counts X 2-3/week. Re-staging every 2 cycles including upper and lower endoscopies. Patients in complete remission (CR) after 6 courses of a planned 6-8 cycles were not offered consolidation with stem cell transplant. Post-treatment evaluation was performed every 3 months for 1 yr, every 4 months for 2 yrs, every 6 months for 2 years, then annually. Results: Of 100 patients registered, one was ineligible and two decided to not receive the treatment after registration, leaving 97 evaluable for analysis of response, survival and toxicity. An analysis of response after the first 6 cycles shows an 87% CR/CRu rate. With a median follow up of 40 months, the 3-year FFS and overall survival (OS) were 67% and 81%, respectively. Adverse factors for FFS were: Grade 4 hematologic toxicity was significant. Five patients died during treatment of sepsis (3), pulmonary hemorrhage (1), and unknown cause (1). Four patients developed myelodysplasia/acute myelogenous leukemia after treatment and while in CR and three have died, for a total of 8 deaths in the study (8%). Conclusion: R-HCVAD alternating with R-M/A without stem cell transplant is an effective regimen for treatment of aggressive untreated MCL, specially for patients ≤ 65 years old. Toxicity is as expected for an intense regimen. This encouraging data warrants continued follow-up and comparison with existing/new therapies in future trials.

Abstract Background: Primary systemic amyloidosis (AL) is a rare plasma cell clonal disorder(8/million) characterized by extracellular deposits of material composed mainly of fragments of light chain immunoglobulin throughout a body. Standard chemotherapy (e.g. melphalan and prednisone) is associated with poor outcomes (typical median survival is between 12–18 months with less than 5% survive 10 years). Autologous stem cell transplant (ASCT) has been increasingly advocated for treatment of AL. However, it is uncertain whether ASCT is better than standard chemotherapy. To address this uncertainty, we undertook a systematic review/meta-analysis to evaluate the efficacy of high-dose chemotherapy and autologous stem-cell transplant (HSCT) versus conventional chemotherapy in patients with AL. Methods: Data search of published studies included Medline [all randomized controlled trials (RCTs)], Cochrane library and hand search of references. Studies were included if they were comparison trials of HSCT versus conventional chemotherapy, regardless if they were RCTs, prospective studies with historical control, or single arm studies. The studies were eligible if patients had biopsy proven AL with at least one major organ involved. Data were extracted on benefits as well as harms (overall survival, event-free survival, response, treatment related mortality, treatment-related morbidity). Results: Out of 34 identified studies only 13 met the inclusion criteria for the current systematic review (2 RCTs, 2 prospective non-randomized trials involving historical control, and 9 single arm trials). Altogether these trials enrolled 1056 patients. Pooled data from 4 trials with controls (RCT and non-RCT) found similar overall survival for ASCT and conventional therapy arms [hazard ratio (HR) of 1.10 (95% CI 0.88, 1.36, p=0.4); p= 0.6]. Analysis of data according to trial design also did not find any difference in survival [HR for RCTs was 1.10 (95% CI 0.88, 1.37) and for non RCTs HR was 0.98 (95% CI 0.29, 3.35)]. The complete hematological response was also similar in both arms in RCTs (Odds ratio [OR]=1.38, 95%CI 0.67, 2.85; p=0.4) and non RCTs (OR=1.78, 95%CI 0.22, 14.65; p=0.32). The pooled proportion of treatment-related deaths in the single arm studies for AHCT was 0.119 (95% CI = 0.09 to 0.14)]. Conclusion: The results from the meta-analysis indicate that there is no statistically significant difference between the treatment effects from high-dose chemotherapy with ASCT and conventional chemotherapy. Hence, the efficacy of ASCT in improving overall survival and complete hematological response remains to be proven.

Abstract Abstract 1038 Poster Board I-60 Background: Outcome of patients (pts) with AML refractory to initial induction is assumed to be poor but the available data is limited. Furthermore, pts refractory to standard dose cytarabine-based regimens may be salvaged with high dose ara-C (HiDaC, defined as daily ara-C dose ≥ 1 g/m2). Information on the outcome of pts refractory to initial HiDaC - based induction is more limited. Aim To better characterize predictors of poor response to HiDaC-based induction and to evaluate the outcome of pts refractory to such induction regimens. Methods: We identified pts treated with induction regimens containing HiDaC at the University of Texas – M D Anderson Cancer Center who did not achieve a compete remission (CR) after one cycle of induction. We examined their pre-treatment characteristics and compared them with similar pts achieving a CR. We also examined their response to salvage chemotherapy and outcome. Results: Among 1179 pts treated with HiDaC-based induction therapy from 1995 to 2009, 285 were primary refractory to one course of induction. Their median age was 59 (range, 18 - 85). Median pretreatment WBC was 9.0 × 109/L (range, 0.3 – 394 × 109/L). Cytogenetics included-5/-7/complex 101 (35%), diploid 85 (30%), other intermediate 98 (34%), favorable 1 (<1%). 165 (58%) pts had antecedent hematological disorder. Induction regimens used included HiDaC with anthracyclines (n=181, 64%), HiDaC with non-anthracycline chemotherapy (fludarabine, clofarabine, topotecan, and troxacitabine) (n=104, 36%) Pts with primary refractory disease were older (Median age 59 vs. 56; p=000004), more likely to have chromosome 5/7 or complex cytogenetic abnormalities (P=0.0001), more likely to have AHD (p=0.0001), and had a higher presentation WBC (P=0.036), but not a higher incidence of FLT3 mutations (p=0.85) than those achieving CR. Primary refractory disease was not more likely with non-anthracycline containing regimens than those with anthracyclines (p=0.58). Salvage chemotherapy included combination chemotherapy in 111 (39%)(non-ara-C regimen in 40, containing ara-C in 71), single agent chemotherapy in 64 (22%), allogeneic stem cell transplant in 22 (8%) and none in 88 (31%). Forty-three (15%) pts responded to salvage including 35 CR and 8 CRp. 114 (58%) pts were resistant and 35 (18%) died; 5 (3%) were lost to follow-up. With a median follow-up of 115 weeks (range 8 – 347 weeks) in pts responding to salvage, 21 pts (7%) were alive and in CR, for at least 6 months including 14 who underwent an allogeneic stem cell transplant (median overall survival for these 21 pts, 30 months; range, 13 to 87 months). Conclusions: Outcome of pts with disease refractory to HiDaC-based induction is poor. Alternative strategies are needed in these pts who are likely to be resistant to standard chemotherapy.

Abstract Abstract 1222 Poster Board I-244 Background Survival for patients with primary CNS lymphoma (PCNSL), in general, is poor with patients requiring frequent chemotherapy treatments or receiving whole-brain radiation therapy, which can potentially result in significant neurologic decline and dementia. Because of the improved survival of high risk patients with aggressive lymphoma undergoing autologous stem cell transplant (ASCT), we began ASCT for patients with PCNSL in first or later remission with chemotherapy sensitive disease. We now update on outcomes of patients who have had at least 100 day follow up post ASCT. Baseline characteristics Between June, 2000 and January, 2009, 22 patients underwent ASCT for PCNSL. Median age at transplant was 50 years old (range 26-67). Median number of prior treatments 1 (range 1-3). Median time from diagnosis to transplant was 7.2 months (range 2.9 to 75.8). Median International Extranodal Working Study Group Prognostic Score: 2 (range 0-3). Disease status at transplant: First CR 10 patients, later CR or PR 12 patients. Results Twenty-two patients underwent ASCT for PCNSL and have a minimum of 100 days follow-up. All patients received BEAM conditioning. Median follow up post-transplant was 30 months (range 3-107 months). Eight patients have relapsed at a median of 217 days (range 40-1349). Of the patients who relapsed, four have died of disease progression and the remaining four are alive after additional therapy. Median overall survival from diagnosis or transplant has not been reached. Median progression free survival from transplant was 70 months. Conclusions Although limited by patient selection and retrospective biases, this review suggests that ASCT for PCNSL demonstrates improved overall survival when compared to historical controls with similar PCNSL Prognostic Scores (2 year survival for patients from diagnosis with PS 2-3 was 48% in a prior published study). ASCT in first remission in patients with PCNSL appears promising and may limit the need for additional therapy which can be myelosuppressive or result in neurologic decline secondary to radiation therapy in patients who are appropriate candidates.

Abstract Abstract 257 The AML-12 randomized phase III trial of EORTC-LG and GIMEMA assessed the efficacy and toxicity of HD-AraC (3 g/sqm/12 hrs for 4 days) combined with daunorubicin (50 mg/sqm/d for 3 days) and etoposide (50 mg/sqm/d for 5 days) vs SD-AraC (100 mg/sqm/d for 10 days) with the same drugs, in previously untreated AML < 61 year old patients (APL excluded). Patients (pts) in complete remission (CR) had to receive consolidation consisting of AraC (500 mg/sqm/12 hrs for 6 days) and daunorubicin. Subsequently an allogeneic (allo-SCT) or autologous stem cell transplantation (auto-SCT) was planned according to donor availability and age. A 2nd randomization had to be done after evaluation of consolidation in pts without a donor: auto-SCT followed or not by low dose IL-2. The aim of the trial was to detect an 8% treatment difference (from 35% to 43%) in the 5-yr overall survival (OS) rate, corresponding to a hazard ratio (HR) of 0.80 (alpha=5%, power=95%); secondary endpoints were response to induction, toxicity, disease-free survival (DFS) from CR. Randomization was performed centrally; the 1st randomization was stratified for age (<46 vs > 45 yrs), performance status, WBC and center. Intent-to-treat analysis was done. From 9/1999 till 1/2008, 2005 pts from 68 centers were randomized. Due to insufficient reporting, 3 centers, who recruited 63 patients, have been excluded from the analysis. The remaining 1942 pts (872 pts entered by EORTC-LG and 1070 by GIMEMA) 969 were randomized in SD-AraC and 973 in HD-AraC arm; among them 25 and 28, respectively, were ineligible, but kept in the analysis. Both arms were comparable with respect to gender, age (median=45 yrs), disease history, initial leukocyte count, PS, FAB and cytogenetics. At a median follow up of 6 yrs, 1114 pts had died. Results: After 1 or 2 courses of induction, CR was achieved in 1430 pts (73.6%); 684 (71.9%) pts (SD-AraC group) vrs 746 (78.7%) pts (HD-AraC group): p=0.002. Resistance was documented in 173 (18.2%) vrs 123 (13%), and death during induction in 85 (8.9%) vrs 71 (7.5%) pts, respectively. Induction toxicity profile and grade was similar in the 2 arms except for conjunctivitis grade 3: HD-AraC>SD-AraC. CR rates for pts<46 yrs were 74.7% (SD-AraC) and 81.4% (HD-AraC) and for pts>45 yrs 66.4% (SD-AraC) and 71.8% (HD-AraC). 634 pts (SD-AraC and 686 (HD-AraC) received a consolidation cycle. Among 765 CR-pts<46 yrs 284 pts had an HLA identical sibling (<46D) and 481 did not or had not been typed (<46NoD). Among 665 CR-pts>45 yrs 225 pts had an HLA identical sibling (>45D) and 440 did not or had not been typed (>45NoD). In the <46D group 211 underwent an allo-SCT and 11 an auto-SCT. In the <46NoD group 274 underwent an auto-SCT and 29 a MUD-SCT; in the >45D group 147 underwent an allo-SCT and 14 an auto-SCT. In the >45NoD group 244 underwent an auto-SCT and 12 a MUD-SCT. Comparisons of treatments arm regarding OS from randomization, DFS and Survival (S) from CR are indicated in the Table. The impact of age on the treatment difference regarding OS was almost significant (p=0.06). In pts >45 who reached CR, the decrease in the relapse rate in the HD-Ara-C arm vrs SD-Ara-C arm (45.5% vs 49.4%) was counterbalanced by an increase in the death in CR rate (18.4% vs 13.2%). Conclusion: The final evaluation of the EORTC-GIMEMA AML-12 trial shows that, with a median follow-up of 6 years, HD-AraC in the induction treatment leads to a significantly higher CR rate than SD-Ara-C and results in improvement in overall survival but only in pts under the age of 46 years.

Abstract Abstract 4554 High-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is currently standard treatment for younger patients with multiple myeloma, resulting in improved survival and response rate compared to conventional chemotherapy. Disease relapse, however, remains almost inevitable and thus the role of two successive (tandem) autologous stem cell transplants has been evaluated in chemorefractory patients as a means of prolonging duration of disease response. We retrospectively analysed the results of nine patients with chemorefractory disease treated at a single UK institution who received tandem ASCT between January 1998 and February 2009. There were six men and three women. Median age at diagnosis was 56 years (range, 42–65 years). Paraprotein isotype was IgG in eight patients and IgA in one patient. Median serum paraprotein level was 41g/L (range 12–73g/L) at presentation. At time of 1st transplant six patients were in stable disease (SD) and three had evidence of progressive disease. Conditioning melphalan dose was 140mg/m2 in all but two patients who received 110mg/m2 and 200mg/m2. Median time between transplants was 3.7 months (range 2.3–6.4 months) with PR and SD being observed in 2/9 and 7/9 patients at time of 2nd transplant. None of the patients reached complete response (CR). One patient received melphalan 140mg/m2 prior to 2nd transplant. The remaining patients received melphalan 200mg/m2. Median follow up after tandem transplant was 54.3 months (range 15.6 –143.6 months). No treatment related mortality was reported. At the time of analysis, six patients were still alive and under follow up with an overall survival (OS) figure for the group of 52% at 10 years from diagnosis (Figure 1). Median progression free survival (PFS) was 20 months from 2nd transplant (range 6.7–62.6 months) (Figure 2). Tandem autologous stem cell transplant in chemorefractory patients has resulted in overall survival similar to autologous stem cell transplant in chemosensitive patients and should be considered in patients with chemorefractory disease.

Abstract Introduction: In younger patients that are transplant-eligible, autologous stem cell transplant (ASCT) prolongs overall survival based on several prospective randomized control trials. Nevertheless, ASCT is not a curative approach and majority of the patient's relapse, requiring further salvage therapeutic options. However, in the face of an ongoing paradigm shift in myeloma therapeutics, there is a significant knowledge gap regarding how patients relapse following ASCT. We analyzed the patterns of relapse among myeloma patients after ASCT. Methodology: We have evaluated a total of 975 patients that underwent ASCT during the period January 2008 through June 2014 from our myeloma database. 273 patients had documented evidence of first relapse post-ASCT on the laboratory parameters, radiologic or pathologic findings based on IMWG criteria for relapse. We categorized the relapses as biochemical vs symptomatic, and described their frequencies and characteristics. Median time of follow up from diagnosis is 68 months and from ASCT is 54 months. We used IBM SPSS version 23.0 to generate the survival statistics. Results: Median time from ASCT to relapse is 20 months. A total of 182 (66.7%) patients (105M, 77F) experienced biochemical relapse, while 91 (33.3%) patients (50M, 41F) had symptomatic relapse. More IgA patients (30.8% vs 23.1%, p=0.06) relapsed as symptomatic myeloma. While characterizing relapses, we did not find any differences in symptomatic relapses by the risk group [high risk (31.3%) vs standard risk (31.9%), p=0.193, ISS stage I (29.3%) vs II (32.9%) vs III (32.8%), p=0.807] or by maintenance [yes (30.7%) vs no (38.1%), p=0.211]. Among the patients that had a symptomatic relapse, presence of new bone lesions (52%) and anemia (42%) are the most common forms of relapse seen. Only 4% presented as hypercalcemia and 1% presented as renal failure illustrating the benefits of closer follow up. Overall survival is similar among patients that relapsed as biochemical or symptomatic relapse (log rank, p=0.105). More importantly, impressive median OS of 145 months from the ASCT among this entire cohort (at median follow up 54 months, figure 1). Conclusions: Two-thirds of the patients relapse as a biochemical relapse post-ASCT. The patterns of biochemical vs symptomatic relapses were similar among patients by maintenance, by risk status and also by the ISS stage. The significant improvement in OS among the entire cohort emphasizes the power of the new therapeutic salvage strategies aimed at gaining the survival advantage even among this selected group of patients undergoing early relapses.

Background: Treatment for primary CNS lymphoma involves a methotrexate-based induction therapy followed by consolidation. The optimal consolidation treatment after induction with a high dose Methotrexate (HD-MTX), Rituximab and Temozolomide regimen has not been fully established. The CALGB 50202 regimen using Etoposide and Cytarabine consolidation was associated with significant toxicity. We sought to review the results of alternative consolidation regimens and evaluate the progression free survival and overall survival. Methods: A retrospective cohort study was conducted to evaluate the efficacy of alternative consolidation regimens such as autologous stem cell transplant and HDMTx alone. Patients diagnosed with primary CNS lymphoma between November 2012 and March 2019 were identified. All patients received the same induction chemotherapy based on the CALGB 50202 protocol. Data was collected for baseline characteristics, progression free survival and overall survival. Results: 38 patients had a diagnosis of primary CNS lymphoma. 15 patients received treatment as per the CALBG 50202 induction protocol with high dose Methotrexate, Rituximab and Temozolomide. Of the 15 patients, 11 patients (69%) achieved a complete remission (CR) after induction therapy. 7 patients received an autologous stem cell transplant for consolidation, 5 patients received HD-MTX alone for consolidation and one patient was placed on Lenalidomide maintenance. 2 patients did not receive any consolidation therapy due to progressive disease and/or death. At a median follow up of 2.7 years for the entire cohort, median PFS was 31.7+ months and median OS was 32.5+ months. At a median follow up of 2.7 years for patients who were consolidated with an autologous stem cell transplant, median PFS and median OS was 27.2+ and 32.5+ months respectively. At a median follow up of 5.5 years for patients who were consolidated with treatments other than transplant, median PFS and OS was 65.6+ months. There were no deaths attributed to treatment related toxicity. To date, 4 patients of the entire cohort have died, with a median survival time among surviving patients of 3.6 years (range, 0.68-7.05 years). There were no deaths attributed to treatment related toxicity. Conclusion: Patients with primary CNS lymphoma who received induction therapy as per CALGB 50202 regimen and received alternative consolidation therapies with either autologous stem cell transplant or HD-MTX based consolidation achieved prolonged PFS and OS comparable if not superior to the Etoposide and Cytarabine consolidation. Results of the ongoing CALGB 51101 trial will determine the utility of EA consolidation. Disclosures No relevant conflicts of interest to declare.

7623 Background: Survival for patient with primary CNS lymphoma (PCNSL), in general, is poor with patients requiring frequent chemotherapy treatments or receiving whole-brain radiation therapy, which can potentially result in significant neurologic decline and dementia. Because of the improved survival of high risk patients with aggressive lymphoma undergoing autologous stem cell transplant (ASCT), we began ASCT for patients with PCNSL in first or later remission with chemotherapy sensitive disease. We now report on outcomes of patients who have had at least 1 year follow up post ASCT. Methods: Between June, 2000 and September, 2004, 11 patients underwent ASCT for PCNSL. The medical records of consenting patients were abstracted for the following information. Median age at transplant was 47 years old (range 30–67). Median number of prior treatments 1 (range 1–3). Median time from diagnosis to transplant was 7.5 months (range 2.9 to 75.8). Median International Extranodal Working Study Group Prognostic Score: 2 (range 0–3). Disease status at transplant: First CR 5 patients, later CR or PR 6 patients. Results: Eleven patients underwent ASCT for PCNSL and have a minimum of 1 year follow-up. All patients received BEAM conditioning. Median follow up was 28.3 months. Four patients have relapsed at a median of 200 days (range 40–523). Of the patients who relapsed, one has died of disease progression and the remaining three are alive after additional therapy. Median overall survival and progression free survival from transplant have not been reached. Two year overall and event free survival are 89% and 61%, respectively. Conclusions: Although limited by patient selection and retrospective biases, this review suggests that ASCT for PCNSL demonstrates improved overall survival when compared to historical controls with similar PCNSL Prognostic Scores (2 year survival for patients from diagnosis with PS 2–3 was 48% in a prior published study). ASCT in first remission in patients with PCNSL appears promising and may limit the need for additional therapy which can be myelosuppressive or result in neurologic decline.

7533 Background: Peripheral T-cell lymphomas (PTCL) have suboptimal outcomes with conventional chemotherapy. Autologous hematopoietic stem cell transplant (AHCT) is a therapeutic strategy for patients in first complete or partial remission (CR1 or PR1), with median progression-free survival (PFS) after AHCT of 36-48% by intent to treat (d’Amore et al JCO 2012, Reimer et al JCO 2009). Romidepsin (romi) is a histone deacetylase inhibitor approved for treatment of relapsed/refractory T-cell lymphoma. We present updated data of the first multicenter study to evaluate PFS of patients (pts) receiving maintenance therapy with romi after AHCT. Methods: This was a phase 2, open-label, investigator-initiated study (expected PFS 45%, desired PFS 70%; success achieved if 15 or more pts out of 25 were progression-free at 2 years post-AHCT). 26 pts transplanted in CR1 or PR1 were evaluable for the primary endpoint of 2-year PFS (Cohort 1, Table). An exploratory cohort (Cohort 2, n=7) enrolled pts either transplanted ≥ CR/PR2 (n=5) or with high risk histologies (n=2). Pts underwent AHCT with carmustine, etoposide, cytarabine and melphalan (BEAM) conditioning. Maintenance romi 14 mg/m2 started days 42-80 post AHCT; every other week through 6 mon, every 3 weeks through 1 year and every 4 weeks through 2 years post AHCT. PFS was estimated by Kaplan-Meier. Results: 47 pts consented; 13 did not receive romi (no AHCT, n=2; relapse before romi, n=3; cardiac comorbidity, n=3, patient declined, n=5). 1 consented pt did not have PTCL. 15 out of the first 25 pts in Cohort 1 were progression free after 2 years; median follow up of 31 mon (21 - 36 mon). Estimated 2-year PFS was 62% (45-83%, 95% CI); median PFS 30 mon (12.0- NA, 95% CI). In Cohort 2, estimated 2-year PFS was 43% (18 – 100, 95% CI); median follow up of 30 mon (range, 24 – 37 mon); median PFS 14 mon (5 – NA, 95% CI). Across cohorts, 5 pts required dose reduction. The most common toxicities (≥10% of pts, all grades) were fatigue (n=24, 73%), decreased platelets (n=16, 48%) and anemia (n=16, 48%). Conclusions: While the study did not meet its desired primary efficacy endpoint, maintenance romi was well-tolerated with an estimated 2-year PFS of 62%, greater than historical data. A larger, randomized study would be needed to determine the superiority of this approach. Clinical trial information: NCT01908777. [Table: see text]
